Application filed July 12, 1907. Serial No. 383,377.

To all whom it may concern:

Be it known that I, OSCAR O. HARRIS, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Harness-Loop Formers and I do declare the following to be a full, clear, and exact description of the invention, reference being had to the accomn tioned character whereby the cost of production may be greatly reduced through saving of time in operation. And a further object is to provide a harness loop former which will be reliable in producing loops of uniform character and accuracy.

The invention consists in an improved harness loop former comprising a novel base adapted to be secured adjustably to a liarness press table and improved forming tools or devices connected to the base in a novel manner for shaping harness loops in coperation with the pressure-bar of the press and jaws on the base, the tools being removable from the base so that different sizes of tools may be substituted therefor; and the invention consists further in the novel parts and combinations and arrangements of elements as hereinafter particularly described and referred to in the appended claims.

Referring to the drawings Figure 1 is a front elevation of a harness loop former constructed substantially in accordance with the invention; Fig. 2, a fragmentary top plan of the base Fig. 3, a top plan view of the complete apparatus; Fig. 4, a vertical sectional view approximately on the line A A in Fig. 3; Fig. 5, a vertical sectional view approxi* mately on the line B B in Fig. 3; Fig. 6, a vertical sectional view approximately on the line C O in Fig. 3; Fig. 7, a fragmentary vertical sectional view approximately on the line A A in Fig. 3; looking forwardly; Fig. 8, a top plan of one of the forming jaws; Fig. 9, a perspective view of a die and holder therefor inverted; Fig. 10, a perspective view of the loop stick; Fig. 11, a perspective view of the bottom mold to coperate with the embossing die; Fig. 12, a perspective view of part of the apparatus; and Fig. 13, a fragmentary vertical sectional view on the line B B in Fig. 3.

Similar reference characters in the several figures of the drawings designate like ele ments or features of construction.

A practical embodiment of the invention comprises a solidly 'formed base 1 of suitable dimensions, the under side of which is Aflat and adapted to rest upon the table of a harness press, the top of the base having suitable flat surfaces, and the .rear part of the base has an integral arm 2 extending horizontally a suitable distance, the main portion of the base having a suitable slot 3 in which is a clamp bolt 4 and a slot 5 in which is a clamp bolt 6 for adjustably securing the base to the press table. The base is provided at the top of one end thereof with a screw-head 7 in which is mounted an adjusting screw S provided with a hand wheel 9, the screw having a guide end 10 in which is a groove 11 to receive the end of a retaining pin 12 for connecting a jaw 13, which is provided, with the screw, the 'aw being ada ted to rest upon the top of t e base 1, and it is provided with a creasing plate 14. The creasing plate of course may be of any suitable pattern or design, being detachable from the jaw as usual, so that other patterns may be used when desired for ornamenting one side of a loop. The screw as will be seen is mounted on one end of the base, preferably at the left hand side of the operator, and in the other end portion of the base it is suitably recessed and provided with a pair of parallel guides 15 and 16 in which is mounted a movable jaw 17 to oppose the adjustable jaw 13, the jaw 17 having also a creasing plate 18 on its working end, and theother end of the jaw is provided with a semi-circular socket bearing 19, the top of the jaw having a socket 20 therein. A link bar 21 is provided for operating the jaw 17 and has a. semi-circular bearing end 21 in which end is a ivot hole 22', the bearing end fitting to t ie socket bearing 19 to form a knuckle joint. A pivot 22 is .connected in the hole 22 Aand has .an arm 23 provided with a projection 24 that enters the socket 20 for holding the jawand the link bar together, and when necessary the link bar may be lifted vertically so'as to withdraw the projection 24, so that a jaw of different pattern may be substitutedfor the aw 17 when desired. of the link bar 21 has a slot` 25 therein arranged horizontally and a vertical pivot pin hole 26 to receive a'pivot pinv27. The base 1 is provided with a post 28 having av bearing 29 in one side thereof to receive the swinging end of the link bar 21, the opposite side of the post having a horizontal recess 30 and a vertical pivot pin hole 31 in which is a pivot pin 32. An operating lever 33 has an arm 34 extending into the recess 30 and connected therein by the pivot pin 32, the operating lever having also an arm 35 entering the slot 25 and connected to the link bar 21 by means of the pivot pin 27, so that normally the link bar is interposed between the aw 17 and the post 28, and when an operating lever is moved to a position shown in dotted lines in Fig. 3, the jaw will be retracted or moved towards the post 28, the end of the link bar21 being drawn away by the arm 35 from the bearing 29 of the post.

In order to attain the desired speed and accuracy in shaping the loops to the desired forms, the pattern tools are connected to the arm 2 of the base, the end portion of the arm having a guide way 36 therein extending crosswise of the arm or so as to be substantially parallel with the line of motion of the movable jaw 17, and in the guideway a slide 37 is mounted through which extends one end of a double ended bolt 38 and 39 having a collar 40 formed integral therewith to serve as a head for two bolts which are provided with nuts-41 and 42, so that the slide 37 may be prevented from accidental withdrawal from the guideway, but permitting its movement longitudinally therein. For shaping the back of the .loop or the rear side of the harness part to which theloop may be connected, a bottom mold is provided which has a shank 43 provided with a hole 44 by which it is connected to the bolt end 38 to rest upon the head 40, the mold 45 being integral with the shank and adapted Ato rest upon the top of the base l between the jaws 13 and 17, the mold having recesses 46 and 47 to clear the metallic parts of the harness, such as buckles or rings. A metallic loop stick 48 is placed upon the bottom mold and its shank and has a hole 49 in one end portion receiving the bolt end 38, the loop stick having an offset portion 50 to clear harness rings or buckles, and

having also a pointed end 51 adapted toV readily enter an unfinished loo the loop stick being gaged by the bolt enc 38 with respect to the bottom mold. A die-holder 52 rests upon the shank of the loop stick and The opposite end c has a hole 53 receiving the bolt end 38, and the thumb-nut 41 is moved down only sufciently to keep the three elements mentioned close together without binding them against the head 40. The die-holder has an offset portion 54 to clear the offset portion 50 of the loop stick, and an embossing die 55 is attachedv to the holder at the under side thereof, and also preferably a metal block 56 is attached to the opposite or upper side of. the die-holder to be engaged by the pressure bar ofthe harness press.

It will be understood that a variety of sizes and shapes of loop sticks and also dies and holders and bottom molds will be provided to suit the various sizes of loops which may be required. It should be understood also that various other connections may be provided in lieu of the link bar 21 and operating lever 33 for holding the jaw 17 in its operative position, and moving it to or from such position.

In practical use the jaw 13 is to be adjusted by means of the screw 8 so that it will set at a properY distance away from the jaw 17. The lever 13 is to be operated to withdraw the jaw 17 and then the harness loop is to be placed on the loop stick 48 as indicated by dotted lines in Fig. 10, the loop stick being free to move as may be necessary away from the jaw 13 to permit of free action of the at-V proper position, and the two jaws will forcibly engage the sides of the loop which may be suitably creased or embossed if the jaws be provided with the proper creasing plates. Then the pressure bar of the press will be o erated so as to forcibly engage the metal b ock or die back 56, and thus force the loop against the bottom mold at the same time causing the die 55 to impress its characters in the top or front of the loop. In some cases however, the bottom mold may not be used, and for plain work also the die 55 may be de void of ornamentation.
